For whatever reason, I think people have gotten more snarky over the past few months. This is best exemplified by looking as the Hasselblad thread that was in response to a post that Kevin did about two weeks ago (as a result of that one, a couple of valued contributors indicated they would be leaving or reducing their presence). I didn't know that Andrew wasn't posting as I mainly look at the printer & paper thread and the articles on the Home Page. I'm disappointed that the collaborative nature of this website has diminished, maybe it was the introduction of the membership fee or Michael's passing. I'm not sure but there sure is something different these days and it's not good.
+1 I've noticed it too.
I think it's the "Trump effect". It seems, with some people at least, it is now more acceptable to be quick with abrupt, poorly thought-out "shots from the lip". Sad really. I see it on media sites, FB and, sadly, here. Hopefully, they are just a vocal minority.
Mark - I know you're looking for an exact example to support Alan's claim and, if I felt like spending the time, I could put my finger on a few threads, but really, it's a change in tone that, obviously, I, too, have picked up on. And, as I said, it's not just here, but elsewhere as well.
